To provide a stretched film, which has excellent impact resistance and oxygen barrier properties and which suppresses the number of pinholes after being bent, a packaging material using the same, and a method for producing the stretched film.The stretched film contains from 80 to 5 parts by mass of a polyamide resin (B) relative to from 20 to 95 parts by mass of a polyamide resin (A), the polyamide resin (A) being an aliphatic polyamide resin, the polyamide resin (B) containing a constituent unit derived from a diamine and a constituent unit derived from a dicarboxylic acid, 70 mol% or more of the constituent unit derived from a diamine being derived from xylylenediamine, from 30 to 70 mol% of the constituent unit derived from a dicarboxylic acid being derived from an α,ω-linear aliphatic dicarboxylic acid having from 4 to 8 carbons, and from 70 to 30 mol% of the constituent unit derived from a dicarboxylic acid being derived from isophthalic acid provided that a total of the constituent units derived from a dicarboxylic acid is not more than 100 mol%. |
